Final answer:
The Canterbury Tales" presents a critical and sometimes satirical examination of human nature, including themes of deceit and a critical perspective on romantic relationships, making it the answer to the question.
Step-by-step explanation:
The story that endorses the idea that you can't trust people because they are deceitful and presents a bitter view of romantic relationships is d) "The Canterbury Tales". Geoffrey Chaucer's famous work, "The Canterbury Tales," consists of several tales narrated by different characters, some of which satirize various social classes and human follies, including the duplicity of people and the complexities of romantic relationships.
In contrast, "Sir Gawain and the Green Knight" tends to focus on the nobility of its characters and the chivalric code, while "Bonny Barbara Allen" is a traditional ballad that centers on love and loss but not necessarily deceit. The choice, "Get Up and Bar the Door," is a humorous folk song addressing the stubbornness between a husband and wife rather than deceit or romantic skepticism.
